Door Sequencer
Description
Door Sequencer
This new door sequencer has following qualities:
No V-Cables necessary.Slight programming with help of 2 push buttons and a coding switch.Switching point adjustable, by which multiple uses on one channel are possible.All four outputs (Gear, 3 Doors)are separately adjustable over the whole servo travel range.Delay time from opening doors and delivering undercarriage adjustable up to 3 sec.Delay time of closing doors adjustable up to 13 sec.Saves last switch position of transmitter.
Three modes of operation:
Mode 1:Gear doors open up, undercarriage out, doors close.Gear doors open up, undercarriage in, doors close.
Mode 2:Gear doors open up, undercarriage out, Gear doors stay open.Undercarriage in, Gear doors close.
Mode 3:Gear doors open up, undercarriage out, 2 doors close, 1 door stays open.2 doors open up, undercarriage in, 3 doors close.

1. Adjusting switching point:_
Turn on transmitter and receiver, set function switch to the “Gear OUT” position._Set coding switch to position SP (Switching Point) _Push (-) button. _Set function switch to the “Gear IN” position. _Push (+) button. _Set coding switch to desired mode.
2. Adjusting gear valve servo end positions (G):_
Gear switch at the transmitter to the “Gear OUT” position._Coding switch to position G. _Push buttons + or - so, that the valve servo delivers the undercarriage. _Gear switch at the transmitter to the “Gear IN” position. _Push buttons + or - so, that the valve servo brings in the undercarriage. _Coding switch to wanted mode, or to next adjustment.
3. Adjusting Gear door servo (D1-D3):_
Gear switch at the transmitter to the “Gear OUT” position. _Coding switch to position D1. _Push buttons + or - so, that the Gear door 1 servo opens. _Gear switch at transmitter to the “Gear IN” position. _Push buttons + or - so, that the Gear door 1 servo closes. _Repeating procedure for Gear door 2 and 3 with the coding switch positions D2 and D3. _Coding switch to wanted mode, or to next adjustment.
4. Adjusting delay time between Gear doors and gear valve (between 1 - 3Sec)_
Gear switch at the transmitter to the “Gear OUT” position. _Coding switch to TIME G. _One push on the buttons changes the delay time approx. 0.5 sec _By toggling the gear switch at the transmitter and pushing the +/- buttons find out the right delay time. _Coding switch to wanted mode, or to next adjustment.
5. Adjusting delay time of Gear doors: (between 4 -13 Sec)_
Gear switch at the transmitter to the “Gear OUT” position. _Coding switch to TIME D. _One push on the buttons changes the delay time approx. 1 sec _By toggling the gear switch at the transmitter and pushing the +/- buttons find out the right delay time. _Coding switch to wanted mode, or to next adjustment.Note:- By use of Jet-Tronics pneumatic valves it is recommended, to check the function of the circuit by usingnormal servos, to understand more easily its operation.- By using mode 3, D3 will be the nose gear door.- If using new electronic components, always perform range check.
